On the way to his final stop in Louisville, Kentucky, Carson picks up a special passenger. Marilyn is desperate for her son, John, to get rid of his dreadlocks and clean up his act. "I just love everything about him. He's free-spirited. He's creative," she says. "But when people look at him now, I think they don't see the real John."

Marilyn says her son, a grad student who works full time, promised he'd cut his hair for graduation. "Recently when I spoke with him he said, 'Mom, why don't you find me a makeover show?'" she says. "I said, 'I can do that, John.' And so here we are."

Together, Carson and Marilyn ambush a stunned John at work. "We've got to unravel the dreads and see what we're working with," Carson says. "Maybe get him in some not-so-bright-blue clothes and make him look cool and young and kind of artistic."
